Exodus 25:20-22

The cherubim will face each other and look down on the atonement cover. With their wings spread above it, they will protect it. Place inside the Ark the stone tablets inscribed with the terms of the covenant, which I will give to you. Then put the atonement cover on top of the Ark. I will meet with you there and talk to you from above the atonement cover between the gold cherubim that hover over the Ark of the Covenant. From there I will give you my commands for the people of Israel.
